Rex begonias are the showboats of the begonia world and are a
type of rhizomatous begonia that are grown for their multicolored leaves.

The leaves come in every color, pattern and shade, and every size and
shape. All Rex Cultorum types are descended from the Indian species B. rex
that was crossed with other types of rhizomatous begonias.

Rex begonias do
bloom but are not grown for their blooms which pale in comparison to their
spectacular leaves.
